| Silica Dimethyl Silylate | Hydrophobic fumed silica that thickens oils and polyols and suspends particles in oils. Provides also thickening properties in the presence of polar solvents (e.g. dipropylene glycol, triethyl citrate or propylene carbonate). Forms transparent gels in oils (e.g. mineral oil, castor oil, plant oils). Uses: Hair care products (e.g. dry shampoos), skin care products, color cosmetics e.g. makeup & powders. Group: Rheology modifiers. Alternative Names: Silane, dichlorodimethyl-, reaction products with silica. CAS No. 68611-44-9. Appearance: White, greyish odorless powder. IUPACName: Dichloro(dimethyl)silane;dioxosilane. Canonical SMILES: C[Si](C)(Cl)Cl.O=[Si]=O. Catalog: CI-HC-0129. |  |
| Hydrophobic Colloidal Silica | Hydrophobic colloidal silica occurs as a light, fine, white or almost white amorphous powder, not wettable by water. Synonyms: Aerosil R972; silica dimethyl silylate; silica hydrophobica colloidalis; silicic acid, silylated; silicon dioxide, silanated. CAS No. 68611-44-9. Product ID: PE-0608. Mole weight: 60.08. Category: Anticaking Agents; Emulsion Stabilizer; Glidant; Suspending Agents; Stabilizer; Viscosity-increasing Agents. Product Keywords: Stabilizers; Suspending Agents; PE-0608; Hydrophobic Colloidal Silica; Anticaking Agents; Emulsion Stabilizer; Glidant; Suspending Agents; Stabilizer; Viscosity-increasing Agents; ; 68611-44-9. UNII: NA. Chemical Name: Silane, dichloro-dimethyl-, reaction products with silica. Grade: Pharmceutical Excipients. Administration route: Oral ; rectal. Dosage Form: Oral tablets; rectal suppositories. Stability and Storage Conditions: Hydrophobic colloidal silica should be stored in a well-closed container. It will not absorb moisture but may still absorb volatile substances owing to its high surface area. Source and Preparation: Hydrophobic colloidal silica is prepared by the flame hydrolysis of chlorosilanes, such as silicon tetrachloride, at 1800°C using a hydrogen-oxygen flame. It is rapidly cooled to create an amorphous product and immediately treated with dichlorodimethyl silane in a fluid bed reactor.The resulting surface is covered with dimethylsilyl groups. Ae |  |
